New guinea impatiens plant named &#39;gruneu 23&#39;

ABSTRACT

‘GrüNeu 23’ is a new variety of  New Guinea Impatiens  that exhibits violet-pink colored flowers.

BOTANICAL CLASSIFICATION

Impatiens hawkeri

VARIETAL DENOMINATION

‘GrüNeu 23’

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct cultivar of Impatiens hawkeri known by the varietal name ‘GrüNeu 23’. The new variety was discovered in The Netherlands. The new variety is a result of cross breeding Seedling #1-27 (female parent) (unpatented) and Seedling #2-07 (male parent) (unpatented). The purpose of the breeding program was to develop a cultivar that exhibited large flowers. The new variety is similar in flower color to its parents, but differs in growing habit and flower size. The new variety was first asexually reproduced by vegetative propagation by cutting in The Netherlands. The new variety has been trial and field tested and has been found to retain its distinctive characteristics and remain true to type through successive asexual propagations. Characteristics that distinguish the new variety from others known to the breeder include:

-   -   Flower color;     -   Growing habit; and     -   Flower size.

The new variety was grown in a 11-21 cm container in The Netherlands. The new variety initiates roots in 8 days at 16° C. A rooted plant is produced in 21 days at average temperatures of 16-21° C. Its rooting habit is round and freely branching.

DESCRIPTION OF THE DRAWING

The accompanying photographic drawing illustrates the new variety, with the color being as nearly true as is possible with color illustrations of this type.

DESCRIPTION OF THE PLANT

The following detailed description sets forth the characteristics of the new cultivar. The data which defines these characteristics were collected by asexual reproductions carried out in The Netherlands. The color readings were taken indoors in a greenhouse on a sunny day. The new variety was sixteen weeks old from rooting and fully flowering when described. Color references are primarily to the R.H.S. Colour Chart of The Royal Horticultural Society of London.
